Mobile Sensor Actuator Gateway On Labs


Published on

This set of APIs provides a suite of tools for reading, storing and manipulating sensor descriptions and data. The tools provide descriptions and data in high-level standardized formats such as OGC SWE SensorML and OGC Observations and Measurements, which can be used in a variety of applications.

Mobile Sensor Actuator Gateway On Labs

  1. 1. Mobile Sensor Actuator Gateway A API networking-application-platform/
  2. 2. Mobile Sensor Actuator Gateway Use the Android SDK to develop applications using the on- board sensors of your mobile phone Easy to use API for retrieving the descriptions and data of the on-board sensors in standardized formats Mobile Sensor Actuator Gateway uses OGC SWE SensorML for descriptions and OGC Observations & Measurements for data 2
  3. 3. Why Mobile Sensor Actuator Gateway? Devices like mobiles are used everywhere and many now are instrumented with a variety of sensors & actuators Low-level Android APIs do not provide sensor information in a high-level, industry standard format Mobile Sensor Actuator Gateway (MSAG) provides simple APIs that are lightweight and straightforward for developers to use MSAG from Ericsson Labs is a sensor & actuator API tailored for rapid prototyping of sensor applications 3
  4. 4. Main Features of MSAG API provides two main calls: – Get sensor descriptions in OGC SWE SensorML format – Get sensor data in OGC Observations & Measurement format MSAG supports the following on-board sensors: – Temperature – Orientation – Magnetic field – Accelerometer API also contains a cache for storage of historical data All sensor readings are geotagged & timestamped 4
  5. 5. MSAG SDK examples Use the sensor descriptions and data from the phone to render sensor information on a map (see Ericsson Mobile Maps) 5
  6. 6. MSAG overview AIDL Interface: Android IPC system ServiceConnection: provides IPC interface Auto-generated stub: provides application API 6
  7. 7. MSAG Client API Library that is easily included in your Android mobile application Supports Android phones with version 1.5 and later Example code below shows getDesc() and getData() methods public void getOperationCode() throws RemoteException { /** Code for showing data on screen */ if( op_code == SHOW_DESC ){ checkCallingPermission( "ericsson.msag.Communicator" ); /** One of the methods of the Communicator interface */ res = communicator.getDesc(); /** Unbind service and disconnect */ unbindService( conn ); }else if( op_code == SHOW_DATA ) { checkCallingPermission( "ericsson.msag.Communicator" ); /** Another method of the Communicator interface */ res = communicator.getData(); /** Unbind service and disconnect */ unbindService( conn ); }else { res = null; } } 7
